In particular, the SCAA was used to test alternate hypotheses on the mechanisms of interaction between the DSWC and the red shrimp population and to estimate reference points for management. Both the yield per recruit analysis and the Statistical Catch at Age model showed that this resource is in overexploitation. Show full item record.
